I apologize for this duplicate post but I am new to AudioKarma and didn't even realize there was a Pioneer Forum until another user pointed it out. I found the following on the Web with respect to the SX-780 and would appreciate any input as to it's validity and whether or not this is applicable to the other SX-xxx models as well. Thank you! - Mark
"This receiver was MADE IN JAPAN (the only true collectable version) and also has the famed Darlington Power Packs. For those who don't know about the Darlingtons, when Pioneer first came out with this receiver, they used inferior output power packs. Pioneer soon learned of the problem and started using the Darlingtons early on in production." STK-0050 = Darlington Power Pack, whether it says "Darlington" on it or not.
